  In such a switch device, a winding stem pipe is attached to the through hole of the watch case, and the shaft portion of the operating member is inserted into the winding stem pipe, and the outer end portion of the winding stem is attached to the shaft portion of the operating member. It has been configured. In this case, a ring member having a plurality of engaging projections is attached to the operation member. The winding stem pipe has a small-diameter portion that is attached to the through hole of the watch case and a large-diameter portion that protrudes to the outside of the watch case, and the engagement convex portion of the ring member is formed on the outer peripheral surface of the large-diameter portion. A plurality of locking grooves that are detachably locked are provided.

  The engaging groove portion includes an attaching / detaching guide groove for moving the engaging convex portion of the ring member attached to the operation member along the axial direction of the winding stem pipe so as to be detachable from the engaging groove portion, and the ring member. A locking groove that restricts and locks the movement of the engaging projection in the axial direction, and a continuous groove that guides the engaging projection of the ring member to either the guide groove or the locking groove.

  For this reason, in this switch device, when the operating member is locked, when the engaging protrusion of the ring member is inserted into the guide groove and pushed in, and the operating member is rotated in this state, the engaging protrusion of the ring member is By moving from the guide groove to the lock groove through the continuous groove, the lock groove restricts the movement of the winding stem pipe in the axial direction with respect to the engaging convex portion, and the operation member is locked in the pushed state. .

  Further, in this switch device, when the operation member is unlocked and the operation member is pulled out, the engagement protrusion of the ring member located in the lock groove is continuously formed from the lock groove by rotating the operation member while pushing it.

Thereby, the elastic part 16 is comprised so that the mountain-shaped part 6a may be elastically deformed in the direction orthogonal to the axial direction of the cylindrical part 15 by the some slit hole 16b.

  That is, as shown in FIGS. 1 to 3, the elastic portion 16 is elastic so that the mountain-shaped portion 16 a is crushed when the mountain-shaped portion 16 a is pressed from the outer peripheral side of the cylindrical portion 15 toward the inner side. By being deformed and being pressed against the outer peripheral surface of the operation shaft portion 12, the outer diameter of the cylindrical portion 15 is substantially the same.

  Further, as shown in FIGS. 1 to 3, the outer end portion of the cylindrical portion 15, that is, the end portion of the cylindrical portion 15 located on the outer side of the watch case 1 is connected to the operating shaft portion 12 of the operating member 7. An engagement hook 17 is provided to be locked in the provided locking groove 18. As shown in FIGS. 3 (a) to 3 (c), the engaging hook 17 has a cylindrical portion that is located opposite to each other at the outer end portion (left end portion in FIG. 3 (c)) of the cylindrical portion 15. By being bent toward the inside of 15, they are provided so as to protrude in directions opposite to each other.

  In this case, as shown in FIGS. 3 (a) and 3 (b), the engagement hook 17 is elastically displaced in the tubular portion 15 in a direction perpendicular to the axial direction of the tubular portion 15. It is desirable that a notch groove 17 a for this purpose is provided on both sides of the engagement hook 17. Further, as shown in FIGS. 1 and 2, the locking groove 18 of the operation shaft portion 12 may be provided in an annular shape on the outer end surface of the operation shaft portion 12 approaching the operation head portion 13.

Are configured to be attached.

  On the other hand, as shown in FIGS. 1 and 2, the position restricting member 9 is fitted and fixed in the large-diameter hole portion 11b of the case body 1a in the through hole 11 of the watch case 1, and in this state, the operation member 7 is fixed. The elastic member 16 of the engagement member 7 is detachably locked in accordance with the movement operation in the axial direction of the engagement member 7, thereby restricting the movement of the operation member 7 in the axial direction.

  That is, as shown in FIGS. 1 and 2, the position regulating member 9 is fitted and fixed in the large-diameter hole portion 11 b of the through hole 11, and the engaging member 7 is axially moved together with the operation shaft portion 12. A cylindrical restriction main body 20 that is movably inserted along the restriction main body 20 and a restriction recess 21 that is provided on the inner peripheral surface of the restriction main body 20 and into which the elastic portion 16 of the engagement member 7 is detachably inserted. I have.

  In this case, as shown in FIGS. 1, 2, and 4, the elastic portion 16 of the engagement member 7 is slid obliquely toward the restriction recess 21 in a direction perpendicular to the axial direction of the operation shaft portion 12. An inclined surface 21a is formed. That is, the inclined surface 21 a is formed with substantially the same inclination as the inclined surface of the mountain-shaped portion 16 a in the elastic portion 16 of the engaging member 7.

  Thereby, as shown in FIG. 1 and FIG. 2, the restricting concave portion 21 has a slope located on one side of the mountain-shaped portion 16 a of the elastic portion 16 when moving in the direction in which the operation shaft portion 12 of the operation member 7 is pulled out. It is configured to be elastically crushed while being slid along the inclined surface 21 a of the regulating recess 21. Further, when the restricting recess 21 moves in the direction in which the operation shaft portion 12 of the operation member 7 is pushed, the inclined surface located on one side of the angled portion 16a of the elastic portion 16 extends along the inclined surface 21a of the restricting recess 21. It is configured to gradually return to elasticity while sliding.

  Incidentally, the end portion of the winding stem 6 is attached to the operation shaft portion 24 of the operation member 7 as shown in FIGS. 1 and 2. Accordingly, the winding stem 6 is configured to move along the axial direction in conjunction with the pulling-out operation and pushing-in operation of the operation member 7 and to rotate in conjunction with the rotation operation of the operation member 7. The winding stem 6 is extended and arranged in a watch module 4 provided in the watch case 1. In this case, the winding stem 6 is biased in the direction in which it is pushed out by the spring force of a spring member (not shown) in the timepiece module 4.

  As shown in FIGS. 1 and 2, the winding stem 6 is configured such that the operating head 13 of the operating member 7 is pushed against the spring force of a spring member (not shown), and the elastic portion of the engaging member 8. 16 is inserted with the operating member 7 when the angled portion 16a is inserted into the restricting recess 21 of the position restricting member 9 and is in contact with the stepped portion 11c in the through hole 11 of the watch case 1. It is configured to be locked with.

  In addition, as shown in FIGS. 1 and 2, the winding stem 6 pulls out the operating head 13 of the operating member 7 together with the spring force of a spring member (not shown), and in the elastic portion 16 of the engaging member 8. When the mountain-shaped portion 16a is elastically deformed so as to be crushed and separated from the restriction recess 21 of the position restriction member 9, the axial lock on the operation member 7 is released.

  Further, as shown in FIGS. 1 and 2, the winding stem 6 is unlocked in the axial direction with respect to the operation member 7, and is biased by the spring force of a spring member (not shown), so that the operation member 7. When the head is moved in the pulling direction, the normal timepiece mode is switched to the time correction mode. When the operation head 23 rotates in this state and the winding stem 6 rotates along with the rotation, the winding stem 6 rotates. The time is adjusted according to the rotation.

Next, the operation of the wristwatch switch device 5 will be described.
When this switch device 5 is used, in the state shown in FIG. 1, the operating head 13 of the operating member 7 protruding outside the watch case 1 is grasped with a finger, and the spring member of the winding stem 6 (not shown). Z)) Pull out together with the spring force. Then, the operating shaft portion 12 of the operating member 7 moves in the pulling direction, and accordingly, the engaging member 8 also moves in the same direction.

  At this time, since the engagement hook 17 provided on the cylindrical portion 15 of the engagement member 8 is engaged with the engagement groove 18 of the operation shaft portion 12, the engagement hook 17 is engaged according to the drawing operation of the operation shaft portion 12. The cylindrical portion 15 of the member 8 moves in the restriction main body portion 20 of the position restriction member 9 in the pulling direction. Then, as shown in FIG. 2, the elastic part 16 provided in the cylindrical part 15 of the engaging member 8 is detached from the restricting recess 21 of the position restricting member 9 while being elastically deformed so as to be crushed.

  That is, the elastic portion 16 includes a mountain-shaped portion 16a provided annularly on the outer peripheral portion of the cylindrical portion 15, and a plurality of slit holes 16b provided in the mountain-shaped portion 16a along the axial direction of the cylindrical portion 15. Thus, when the cylindrical portion 15 of the engaging member 8 moves in the pulling direction together with the operation shaft portion 12, the slope located on one side of the mountain-shaped portion 16 a is the inclination of the restriction recess 21 of the position restriction member 9. It moves so as to be elastically pushed down along the surface 21a.

  For this reason, the angled portion 16 a of the elastic portion 16 is elastically deformed so as to be gradually crushed in accordance with the pulling operation of the operation shaft portion 12. When the chevron portion 16a is crushed, the chevron portion 16a is pressed against the outer peripheral surface of the operation shaft portion 12 to have the same cylindrical shape as the tubular portion 15, and the crushed chevron portion 16a is positioned. The inside of the regulation main body 20 of the member 9 is moved in the pulling direction.

  Thereby, the lock by the elastic portion 16 of the engaging member 8 with respect to the position restricting member 9 is released, the winding stem 6 moves in the pulling direction together with the operation member 7, and the timepiece mode of the timepiece module 4 is switched to the time correction mode. When the operating head 23 is rotated in this state, the winding stem 6 is rotated along with the rotation, and the time is adjusted according to the rotation of the winding stem 6.

  On the other hand, when the switch device 5 is not used, in the state shown in FIG. 2, the operating head 13 of the operating member 7 is moved against the spring force of the spring member (not shown) of the winding stem 6. Push inward. Then, the operation shaft portion 12 of the operation member 7 moves in the push-in direction, and accordingly, the engagement member 8 also moves in the same direction. At this time, since the engagement hook 17 provided on the cylindrical portion 15 of the engagement member 8 is engaged with the engagement groove 18 of the operation shaft portion 12, the engagement is performed according to the pushing operation of the operation shaft portion 12. The tubular portion 15 of the member 8 moves in the restricting main body portion 20 of the position restricting member 9 in the pushing direction.

  As shown in FIG. 1, when the elastic portion 16 provided in the cylindrical portion 15 of the engagement member 8 corresponds to the restriction recess 21 of the position restriction member 9, the position restriction member 9 is restored while the elastic portion 16 is elastically restored. Is inserted into the restriction recess 21. That is, since the elastic portion 16 has the mountain-shaped portion 16a annularly provided on the outer peripheral portion of the cylindrical portion 15 being crushed in the same shape as the cylindrical portion 15, the mountain-shaped portion 16a in the crushed state is When it corresponds to the restricting recess 21 of the position restricting member 9, it gradually recovers elastically.

  At this time, the slope of the elastic member 16 of the engaging member 8 that is located on one side of the mountain-shaped portion 16 a slides so as to be elastically pushed up along the inclined surface 21 a of the restricting recess 21 of the position restricting member 9. For this reason, the angled portion 16 a of the elastic portion 16 is inserted into the regulating recess 21 while gradually returning to elasticity in response to the pushing operation of the operation shaft portion 12. When the chevron 16 a inserted into the restricting recess 21 abuts on the step 11 c in the through hole 11 of the wristwatch case 1, the chevron 16 a of the elastic part 16 is regulated by the position regulating member 9.

  Thereby, in a state where the operation member 7 is pushed in, the elastic portion 16 of the engaging member 8 is position-regulated by the position-regulating member 9 and locked. In this state, the winding stem 6 is pushed into the timepiece module 4 against the spring force of a spring member (not shown), so that the time adjustment mode is switched to the normal timepiece mode. For this reason, even if the operation head 13 of the operation member 7 is rotated and the winding stem 6 is rotated, the switch is not operated and the time is not corrected.

  Thus, according to the wristwatch switch device 5, the wristwatch case 1 having the through-hole 11, the operation shaft portion 12 inserted into the through-hole 11 of the watchcase 1, and the outer end of the operation shaft portion 12 An operation member 7 having an operation head 13 provided in the part, an engagement member 8 having an elastic part 16 elastically deforming in a direction orthogonal to the axial direction of the operation shaft part 12 of the operation member 7, and an operation A position restricting member 9 for restricting movement of the operating member 7 in the axial direction by engaging and disengaging the elastic portion 16 of the engaging member 7 in accordance with the moving operation of the member 7 in the axial direction; Since it is provided, the operation member 7 can be easily locked and unlocked with a simple operation.

  That is, in the wristwatch switch device 5, the elastic portion 16 of the engaging member 8 is elastically deformed by simply pulling out the operating head 13 of the operating member 7 without rotating it and moving the operating shaft 12 in the axial direction. Thus, the engagement of the elastic portion 16 with respect to the position restricting member 9 can be released, and in this state, the operation head portion 13 of the operation member 7 is pushed in without rotating and the operation shaft portion 12 is simply moved in the axial direction. The elastic member 16 of the engaging member 8 can be elastically restored and locked to the position restricting member 9. For this reason, it is not necessary to rotate the operation member 7, and the operation member 7 can be easily locked and unlocked by simple operations such as a pull-out operation and a push-in operation.

  In this case, the engaging member 8 has a cylindrical portion 15 attached to the outer peripheral surface of the operating shaft portion 12 of the operating member 7, and the cylindrical portion 15 is provided with an elastic portion 16, thereby forming a cylindrical shape. The cylindrical portion 15 can be easily mounted on the outer peripheral surface of the operation shaft portion 12 simply by inserting the operation shaft portion 12 of the operation member 7 into the portion 15, whereby the elastic portion 16 can be attached to the operation shaft of the operation member 7. It can be reliably and satisfactorily attached to the portion 12.

  That is, the engagement member 8 is formed with an engagement hook 17 protruding from the end of the cylindrical portion 15 toward the inner side of the cylindrical portion 15, and the engagement hook 17 is an operation shaft portion of the operation member 7. The cylindrical portion 15 is moved with respect to the operating shaft portion 12 without being moved in the axial direction of the operating shaft portion 12 by being locked in the locking groove 18 provided on the outer peripheral surface of the cylindrical portion 15. Since it can be reliably attached, the attachment structure of the cylindrical portion 15 to the operation shaft portion 12 is simple, and the cylindrical portion 15 can be easily attached to the operation shaft portion 12.

  In addition, the elastic portion 16 is formed at the inner end portion which is one end portion of the cylindrical portion 15 along the outer periphery thereof, and is formed along the axial direction of the cylindrical portion 15 at the mountain shape portion 16a. The angled portion 16a is elastically deformed in a direction perpendicular to the axial direction of the cylindrical portion 15 by the plurality of slit holes 16b, thereby making the elastic portion 16 the cylindrical portion 15. It can be formed easily and easily.

  In this case, the elastic portion 16 is elastically deformed so that the mountain-shaped portion 16a is crushed because the mountain-shaped portion 16a is elastically deformed in the direction orthogonal to the axial direction of the cylindrical portion 15 by the plurality of slit holes 16b. Thus, the locking of the mountain-shaped portion 16a by the position regulating member 9 can be released, and the mountain-shaped portion 16a in the crushed state is elastically restored to the mountain shape, so that the mountain-shaped portion 16a with respect to the position regulating member 9 is restored. Can be locked.

  In addition, the position restricting member 9 is fixed in the through hole 11 of the watch case 1, and the cylindrical restricting main body 20 into which the engaging member 8 is inserted so as to be movable along the axial direction together with the operation shaft 12. And a restricting recess 21 that is provided on the inner peripheral surface of the restricting main body 20 and into which the elastic portion 16 is detachably inserted. Therefore, the elastic portion 16 engages with the restricting recess 21 of the position restricting member 9. The operating member 7 can be locked at the time, and when the engaging member 8 moves along the axial direction together with the operating shaft portion 12, the elastic portion 16 is elastically crushed from the inside of the regulating recess 21. It can be made to detach | leave, and the lock | rock of the operation member 7 can be cancelled | released by this.

  That is, when the engaging member 8 moves along the axial direction together with the operation shaft portion 12, the position restricting member 9 elastically crushes the mountain-shaped portion 16 a of the elastic portion 16 and separates it from the restricting recess 21. Thus, the lock of the operation member 7 by the mountain-shaped portion 16a can be released, and when the crushed mountain-shaped portion 16a corresponds to the regulating recess 21, the mountain-shaped portion 16a is elastically returned and regulated. The operation member 7 can be locked by the engagement of the mountain-shaped portion 16 a with the restricting recess 21.

  In this case, the restricting recess 21 is formed with an inclined surface 21a for sliding the elastic portion 16 obliquely in a direction orthogonal to the axial direction of the operation shaft portion 12, whereby the engaging member When the lock 8 is moved together with the operating shaft 12 in the pulling direction to release the lock, the slope located on one side of the mountain-shaped portion 16a can be elastically pushed down along the inclined surface 21a of the restricting recess 21, so that elasticity The angle portion 16a of the portion 16 can be elastically deformed so as to be gradually crushed in accordance with the pulling operation of the operation shaft portion 12, whereby the angle shape portion 16a can be smoothly and satisfactorily detached from the restriction recess 21. .

  Further, when the engaging member 8 is moved together with the operation shaft portion 12 in the pushing direction to be locked, the inclined surface located on one side of the mountain-shaped portion 16a when the crushed mountain-shaped portion 16a corresponds to the restricting concave portion 21. Can be elastically restored so as to be elastically pushed up along the inclined surface 21a of the restricting recess 21, so that the angled portion 16a is gradually elastically returned in accordance with the pushing operation of the operation shaft portion 12, and is then moved into the restricting recess 21. Thus, the chevron 16a can be smoothly and reliably engaged in the regulating recess 21.

That is, the position restricting member 30 is a cylindrical restricting main body portion that the engaging member 8 is inserted in the axial direction together with the operation shaft portion 12 while being fixed in the through hole 11 of the watch case 1. 31 and first and second restricting recesses 32 and 33 provided on the inner peripheral surface of the restricting main body 31 and removably inserted into the elastic portion 16 of the engaging member 8.

  In this case, as shown in FIGS. 5 to 7, the first and second restricting recesses 32 and 33 are respectively provided at a plurality of locations along the axial direction on the inner peripheral surface of the restricting main body 31. That is, the 1st control recessed part 32 is cyclically | annularly provided in the internal peripheral surface in the inner end part of the control main body part 31 located in the inner side of the wristwatch case 1 similarly to 1st Embodiment. Also in this case, the first restriction recess 32 is formed with an inclined surface 32 a for sliding the elastic portion 16 obliquely in a direction orthogonal to the axial direction of the operation shaft portion 12.

  Moreover, the 2nd control recessed part 33 is cyclically | annularly provided in the internal peripheral surface located in the intermediate part in the axial direction of the control main-body part 31, as shown in FIGS. In the second restricting recess 33, a pair of inclined surfaces 33a for sliding the elastic portion 16 obliquely in the direction orthogonal to the axial direction of the operation shaft portion 12 is formed in a V shape. That is, the pair of V-shaped inclined surfaces 33 a is also formed with substantially the same inclination as each inclined surface of the mountain-shaped portion 16 a of the elastic portion 16.

  Thereby, as shown in FIGS. 5 to 7, the second restriction recess 33 moves in the direction in which the operation shaft portion 12 is pulled out, and the second restriction recess 33 is crushed in the state where the mountain-shaped portion 16 a of the elastic portion 16 is crushed. When corresponding to the recess 33, the crushed chevron 16a is gradually elastically restored while sliding along the inclined surfaces 33a of the second restricting recess 33, so that the second restricting with a click feeling is achieved. It is configured to be engaged with the recess 33 and to be regulated at the pull-out position.

  Further, as shown in FIGS. 5 to 7, the second restriction recess 33 is moved when the operation shaft portion 12 is pushed in the state in which the angle portion 16 of the elastic portion 16 is inserted and engaged. The angled portion 16a is elastically pushed in the direction of being crushed while sliding along the inclined surfaces 33a of the second restricting recess 33, thereby pressing the angled portion 16a against the outer peripheral surface of the operation shaft portion 12. It is comprised so that it may become the same cylindrical shape as the outer diameter of 15.

Next, the operation of the wristwatch switch device 29 will be described.
When this switch device 29 is used, in the state shown in FIG. 5, the operating head 13 of the operating member 7 protruding outside the watch case 1 is grasped with a finger, and the spring member of the winding stem 6 (not shown). Z)) Pull out together with the spring force. Then, as in the first embodiment, the operation shaft portion 12 of the operation member 7 moves in the pull-out direction, and the engagement member 8 also moves in the same direction.

  Then, as in the first embodiment, the elastic portion 16 provided in the cylindrical portion 15 of the engaging member 8 is detached from the first restricting recess 32 of the position restricting member 30 while being elastically deformed. That is, the elastic portion 16 has a slope located on one side of the mountain-shaped portion 16 a on the inclined surface 32 a of the first restricting recess 32 when the cylindrical portion 15 of the engaging member 8 moves in the pulling direction together with the operation shaft portion 12. It moves so that it can be elastically pushed down along.

  For this reason, the angled portion 16 a of the elastic portion 16 is elastically deformed so as to be gradually crushed in accordance with the pulling operation of the operation shaft portion 12. And if the mountain-shaped part 16a is crushed and pressed against the outer peripheral surface of the operation shaft part 12, the mountain-shaped part 16a becomes the same cylindrical shape as the cylindrical part 15 as in the first embodiment, and this crushed state The chevron 16a moves in the pull-out direction within the restriction main body 31 of the position restriction member 30.

  Then, when the crushed elastic part 16 moves to the second restriction recess 33 of the position restricting member 30, the crushed elastic part 16 is elastically restored as shown in FIG. Insert into the second restriction recess 33. That is, the elastic portion 16 has the mountain-shaped portion 16 a of the cylindrical portion 15 that is crushed in the same shape as the cylindrical portion 15, so that the crushed mountain-shaped portion 16 a corresponds to the second restricting recess 33. , Gradually return to elasticity.

  At this time, each slope of the chevron 16a in the elastic part 16 of the engagement member 8 slides so as to be elastically pushed up along each slope 33a of the second restricting recess 33. For this reason, the chevron 16a of the elastic portion 16 is inserted into the second restricting recess 33 with a click feeling while gradually returning elastically in accordance with the pulling operation of the operation shaft portion 12.

  Thereby, the lock of the elastic portion 16 of the engaging member 8 with respect to the first restricting recess 32 in the position restricting member 30 is released, the winding stem 6 moves in the pulling direction together with the operation member 7, and the timepiece mode of the timepiece module 4 is changed to the time. Switch to correction mode. When the operating head 23 is rotated in this state, the winding stem 6 rotates with the rotation as in the first embodiment, and the time is corrected according to the rotation of the winding stem 6.

  On the other hand, when the switch device 29 is not used, the operation head 13 of the operation member 7 is moved against the spring force of the spring member (not shown) of the winding stem 6 in the state shown in FIG. Push inward. Then, the operation shaft portion 12 of the operation member 7 moves in the push-in direction, and accordingly, the engagement member 8 also moves in the same direction.

  At this time, the elastic portion 16 provided in the cylindrical portion 15 of the engagement member 8 is detached from the second restriction recess 33 of the position restriction member 30 while being elastically deformed. That is, the elastic portion 16 has the inclined surface 33a of the second regulating recess 33 whose inclined surface located on one side of the mountain-shaped portion 16a when the cylindrical portion 15 of the engaging member 8 moves in the pushing direction together with the operation shaft portion 12. Among them, it slides so as to be elastically pushed down along the inclined surface 33a located in the pushing direction.

  For this reason, the angled portion 16 a of the elastic portion 16 is elastically deformed so as to be gradually crushed according to the pushing operation of the operation shaft portion 12. When the chevron portion 16a is crushed and pressed against the outer peripheral surface of the operation shaft portion 12, the chevron portion 16a becomes the same cylindrical shape as the tubular portion 15, and the crushed chevron portion 16a is positioned. The inside of the regulation main body 31 of the member 30 moves in the pushing direction.

  Then, when the crushed elastic portion 16 moves to the first restriction recess 32 of the position restricting member 30 and responds, the crushed elastic portion 16 is elastically restored as shown in FIG. It is inserted toward the first restriction recess 32. That is, since the elastic portion 16 has the mountain-shaped portion 16a annularly provided on the outer peripheral portion of the tubular portion 15 being crushed in the same shape as the tubular portion 15, the crushed mountain-shaped portion 16a is the first portion. When it corresponds to the restricting recess 32, it is gradually elastically restored.

  At this time, the inclined surface located on one side of the mountain-shaped portion 16a slides so as to be elastically pushed up along the inclined surface 32a of the first regulating recess 32. For this reason, the chevron 16a is inserted into the first restricting recess 32 with a click feeling while gradually restoring its elasticity in response to the pushing operation of the operating shaft 12. When the chevron portion 16 a inserted into the first restricting recess 32 abuts on the step portion 11 c in the through hole 11 of the watch case 1, the chevron portion 16 a is restricted by the position restricting member 30.

  Thereby, in a state where the operation member 7 is pushed in, the position of the elastic portion 16 of the engagement member 8 is restricted by the first restriction recess 32 of the position restriction member 30, and the operation member 7 is locked. In this state, the winding stem 6 is pushed into the timepiece module 4 against the spring force of a spring member (not shown), so that the time adjustment mode is switched to the normal timepiece mode. For this reason, even if the operation head 13 of the operation member 7 is rotated and the winding stem 6 is rotated, the switch operation is not performed and the time is not corrected, as in the first embodiment.

  As described above, according to the switch device 29 of the wristwatch, the first and second restricting recesses are provided on the inner peripheral surface of the restricting main body 31 of the position restricting member 30 in addition to the same effects as the first embodiment. 32 and 33 are provided at a plurality of locations in the axial direction of the restriction main body 31, so that when the operation member 7 is pulled out and when the operation member 7 is pushed in, the operation member 7 is reliably and well positioned. can do.

Thus, the pull-out position of the operation member 7 can be restricted, and when the operation member 7 is pushed in, the elastic portion 16 of the engagement member 8 is separated from the second restriction recess 33 of the position restriction member 30 to be 1 It can be made to engage with the control recessed part 32, and, thereby, the pushing position of the operation member 7 can be controlled.

  Further, in this switch device 29, when the operating member 7 is pulled out, the elastic portion 16 of the engaging member 8 is detached from the first restricting recess 32 of the position restricting member 30 and is elastically engaged with the second restricting recess 33. Therefore, the operating member 7 can be regulated to the pulling position with a click feeling, and the elastic portion 16 of the engaging member 8 is detached from the second regulating recess 33 of the position regulating member 30 when the operating member 7 is pushed. Thus, the operating member 7 can be restricted to the pushed-in position with a click feeling.

  That is, according to the switch device 29, when the operation member 7 is pulled out, the mountain-shaped portion 16 a of the elastic portion 16 is disengaged in a state of being crushed from the first restricting recess 32 of the position restricting member 30, and is crushed. Since the mountain-shaped portion 16a in the bent state is elastically restored and engaged with the second restricting recess 33, the operation member 7 can be restricted to the pull-out position with a click feeling, whereby the operation member 7 can be pulled out reliably and satisfactorily. Can be operated.

  Further, according to the switch device 29, when the operating member 7 is pushed in, the mountain-shaped portion 16a of the elastic portion 16 is disengaged from the second restricting concave portion 33 of the position restricting member 30 and is crushed. Since the mountain-shaped portion 16a in the bent state is elastically restored and engaged with the first restriction recess 32, the operation member 7 can be restricted to the pushed-in position with a click feeling, and thereby the operation member 7 can be pulled out reliably and satisfactorily. Can be operated.

  In addition, in 2nd Embodiment mentioned above, although the case where the 1st and 2nd control recessed parts 32 and 33 were provided in the internal peripheral surface of the control main body part 31 of the position control member 30 was described, not only this, For example, three or more restriction recesses may be provided.

  In the second embodiment described above, the pair of V-shaped inclined surfaces 33a of the second restricting concave portion 33 are formed with substantially the same inclination as the inclined surfaces of the mountain-shaped portions 16a of the elastic portion 16. Not limited to this, the V-shaped depth of the second restriction recess 33 may be shallower than the mountain-shaped portion 16 a of the elastic portion 16. Further, the pair of V-shaped inclined surfaces 33 a of the second restricting recess 33 may be formed so as to be inclined more gently than each inclined surface of the mountain-shaped portion 16 a of the elastic portion 16. By doing in this way, when pushing in the operation member 7, the operation member 7 can be smoothly controlled to a pushing position with a click feeling, and the operation member 7 can be pulled out reliably and satisfactorily.
